PAINT AND VARNISH BEMOVER AND PROCESS DI PREPARING THE Specification ofLetters Patent.

Patented March 24, 1908.

To all whom it may concern." Be it known that I, LEIen'roN KRAMER, a citizen of the United States, residing in Philadel hia, Pennsylvania, have invented cer- 5 'tain mprovements in Paint andVa'rnish Re-- movers and Processes of Preparin the Same,

of which the following is a specification.

One object of my invention is toprovide a compound which may be applied to surfaces from which it is desired to remove paint or varnish, and which will so act upon this paint or varnish as to soften'or cut it to such an extent that it may be readily removed by scraping or by mere] wipingoff the surface. It is further desire l to provide a compound having the above noted qualities, which, in

addition shall be'solid or semi-solid and capable of remaining on vertical or inclined sur-.

its functlons as above indicated, shall-have. no objectionable qualities, that is to say,

shall have no injurious effect on the hands of the person using it nor possess any objectionable 'odor. A further ob'ect of myinvention is to providea' rocess or the manufacture of my improve compound.

In carrying out my invention I mix one half pound of ulverized stearic acid and three'quarterso a int offlard oil, thereb ,forming' a pasty or. ough like mass. This dissolve in a solution containing three pints of methylor denatured alcohol, one pint-of 40. ben'zol or toluol, and one pint of acetone.

ln'place'of the acetone, I may, if desired, use one pint of' asolene or one mt of carbon tetrachlorid. Ibo-resulting so ution mag be om used, by 8. reading it over surfaces 4p which it is esired to remove paint or varnish.

In such case, the of steam; acld and U lard oil forms a protecting fil'm which prevents the evaporation of those substances of the solution which tend to cut, remove or soften the paint or varnish, and this film causes the paint or varnish to remain in the softened condition-for extended intervals of time, .so that relativel large surfaces may have my solution app 'ed to them for the purpose of're'moving paint or varnish thereon, after which itwith the softened paint etc., may be removed by wiping or scraping when desired,

I claim:' v

1. A paint and varnish remover consisting 6.0

v of afatty acid and a fatty oil in combination with a substance capable of softening or cutting paint and varnish. l e

2. A paint andfvarnish remover consisting of a fatty acid and an oil, dissolved in a solu- 5 tion containing alcohol, benzol and acetone. 3. A aintand varnish remover consisting of stearlc acid and laid oil in a.soluti0n containing'a substance capable of cutting paint or varnish.

4. A paint and varnish remover which consists of stearic acid, lard oil, an alcohol body, benzol and acetone.

5. A paint and varnish remover which consists in three pints of alcohol, one pint of 'ben- 7 zol, one pint of acetone, one half pound of. stearic acid and three quarters of a pint of lard oil. p

6. The process of preparing a paint and varnish remover which consists in mixin a body of stearic acid with lard oil and issolving the resulting mass in a solution containing an alcohol, benzol and acetone, in substantially the, proportions specified.

In testimony whereof, I have signed my',85.'

name to this specification, inthe presence of two subscribing witnesses.
